Nah, I think you're missing my point.
Direct access to link properties is probably an "advanced" operation.
(Maybe instead of "linkprop" call it "show properties" :-)
What should be "relatively" terse is the show-<linktype>.
In that case, the show-<linktype> includes the most commonly asked for
information... I'd propose that this is:
For all types:
* MTU
* link state (up or down)
For ethernet:
* current link speed, duplex, and whether the link is forced or not.
* whether flow control (pause/asmpause) is supported
* security == none (maybe in the future 802.1x or "linksec"?) ....
maybe suppress this for unsecured links?
For wifi:
* current link speed, mode, and essid
* current security model (wep, wpa, open, etc.)
* signal quality
* current channel
* if the radio is off, then the signal quality can report "off"
(I'd leave "powermode" as an "advanced" property unlikely to be
accessed by the typical end-user. )
For 3G networks (not yet supported, but I'm putting it here as an example):
* current band, link quality and speed if the chipset supports
reporting it (some do, some don't)
* APN (a network name, its like an SSID)
I think what we have for vlans and aggrs (show-vlan and show-aggr) is
pretty good already.
